GHSA-j443-wcqq-xprh
Summary
A critical vulnerability has been identified at https://security.snyk.io/package/linux/chainguard:latest/terraform-provider-sendgrid, associated with the underlying Go version.
If the server's TLS configuration is mutated between connections — for example, a CA is removed from the trusted list via Config.Clone() combined with modification or GetConfigForClient — the resumed handshake still succeeds using the cached session. The certificate is not re-checked against the updated CA list.
As a result, a client whose CA was revoked or removed between the first and second connection could still establish a connection on the resumed session.
